Bayern were knocked out of the Champions League by eventual winners Real in 2017 and 2018 at the quarter final and semi final stage respectively, with both ties shrouded in controversy.
As of this season, VAR is set to be used in the Champions League from the quarter finals onwards, but it has come too late for Vidal who seemingly still feels he has twice been denied what he believes should have been his.
"[With VAR] I would have won the last two Champion Leagues," the Chilean told Mundo Deportivo.
"It's right [to have VAR]. Now, after a goal it will be necessary to be cautious and wait a bit before celebrating. The feeling of having to stop is unusual, but clearly it will be fair for everyone."
He played in the 2015 final against his current club but was on the receiving end of a 3-1 defeat as Barça completed an historic treble for the second time.
Now that he has joined the Catalans after leaving Bayern for around €20m in the summer, Vidal has his eyes firmly on winning it all.
"Win everything, that is the goal. That's what I came for," he said.
"I know that Barcelona has won it many times, but I want to win it too. I want to win everything, because there are new titles for me, and my dream is to win the Champions League."
